Bote-Cote Timber Preservative Additive
Timber Preservative Additive is a thin liquid which reacts with Bote-Cote to reduce its viscosity, enables it to penetrate more deeply into a timber surface to carry the timber preservative into the timber. TPA is not a solvent and does not evaporate, as such liquids can leave a porous layer which would permit easy penetration of water.
